Php/Ajax/Javascript developer needed

Need a PHP / Ajax / Javascript developer to tweak a few pages of a game site: 1. Fix Profile page by a) allowing users to publish information about themselves (about me field) b) propose features (Freelancer to suggest features/functionality in their BID) c) allow linkage to User's FB/Twitter pages d) link to "Rate user" Page to allow others to rate user (Rate User already exists but may need to be fixed) 2. Fix the Account Management page by a) correcting layout problems b) change form entries into Ajax c) list user's purchased avatars and allow them to pick a default avatar 3) Create a script to allow users to upon login, based on certain business rules and criteria purchase avatars and icons. These icons should be then tied to a users account and the user can pick the default avatar in their account management page and it will be displayed in the profile pages 4) Fix the Tournament results page to paginate the number of tournament results to be displayed (pagination script already exists, you must integrate the two) 5. Fix the layout problem in Hall of fame page where past tournament results are written to. Current problem is when the number of completed tournaments is not divisible by four they sometimes don't get shown in a neat grid 6. The games in the site are integrated with Facebook. However, we do not use open id or anything like that. We have our own registration form. At the moment then, if you create an account using FB you cannot login using the main site because the FB login doesn't set up the password (Or username) fields in the database. An additional login form using the FB api should be written. We can provide the required documentation Please when you bid, let me know your total project and also individual tasks otherwise bids will not be looked at knowledge of UNIX is required Thanks
